CVE-2026-41699Network attack vector

Unauthenticated remote code execution via pagination deserialization

Published Jun 11, 2026 · Updated Jun 11, 2026

Unsafe deserialization in affected Spring for GraphQL releases allows remote attackers to execute code through paginated queries. Connection-field request processing instantiates or deserializes attacker-controlled pagination data through exploitable classes on the application classpath; Spring has not identified those classes publicly. The application must expose a paginated Connection field and use 1.3.0 through 1.3.8, 1.4.0 through 1.4.5, or 2.0.0 through 2.0.3.
